The 10 & 20 amp 12 volt Tesla Solar Tracker 5’s have been upgraded to the new EX version, which stands for EXTREME.

They’re 99.5%+ EFFICIENT and are more bulletproof than ever.

When the battery is pushed to the top, it will unlatch the SCRs (turn off a type of switch) for 6 seconds and the battery will settle down a bit and then turn back on.

These are also available at a 20% DISCOUNT, which will be expiring soon. The links are below the video so make sure to get your hands on the world’s best 10 & 20 amp solar charge controller for 12 volt batteries!

From the beginning, we have stated that the low light panels are superior to crystalline panels. Although they have a bigger footprint for the same wattage and are considered lower efficiency, in real world conditions, they actually give you more electricity than the higher efficiency crystalline panels.

A few months ago, an important breakthrough was announced for low light cells that allowed 22.1% of the sunlight hitting them to be converted to electricity. That is about half of the record of 40% for crystalline panels, but is a huge step in having the low light panels be more acceptable to the general solar market. Too many people see the current efficiency of the low light panels and think they’re not good enough, but again, in real world conditions, they give you more electricity overall since they can produce during cloudy skies and even with marginal light from sunrise to sunset.

These high efficiency low light cells are black silicon cells, which simply soak up more light than their crystalline cousins. Although crystalline cells work mostly on invisible infrared light and the traditional amorphous thin film low light panels work on blue and green, these black silicon cells are structured to absorb as much of the infrared and visible light as possible so it benefits from the best of both worlds.

CIGS (Copper Indium Gallium Selinide) cells also work in both ranges, but they’re not readily available, very expensive and the efficiency isn’t that great so hopefully we’re at the game-changing stage with low light panels, which literally can change the face of the solar industry.
